OPEN-.FACE SLEEVE SEAL.

Application filed March 13, 1924. Serial No. 698,937.

To all whom it may concern.'

Be it known that I, EDWARD J. BROOKS,

a citizen of the United States, and a resident of East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Open- Face Sleeve Seals, of which the following is a specification.

This invention relates to a sleeve seal used l0 to lock overlapping ends of metallic strapping, and has more particularly reference to an improvement upon the seal disclosed in application Ser. No. 543,789 iiled March 14, 1922, the object of the improvement being to facilitate the process of forming the seal around the strap ends.

In the accompanying drawings the invention is disclosed in a concrete and preferred form in which Fig. 1 is a perspective view of the sealing member.

Fig. 2 is a sectional view showing overlapped strap ends and the sealing member in straddled position thereto.

Fig. 3 is a sectional view showing the wings of the seal bent beneath the strap ends.

Fig. 4 is a diagrammatic view showing the tightening step of the sealing operation.

Fig. 5 is a sectional view showing the strap ends and seal interlocked.

Fig. 6 is a plan view of the finished seal.

'The open face seal member 1 consisting of a main portion 2 and upstanding wings 35 8 is placed over the overlapped strap ends 4 and 5, as shown in Fig. 2, between the dies of a tool such as is shown in application Ser. No. 548,789 filed March 14, 1922.

The tool is then actuated part way to fold the wings beneath the strapping as indicated in Fig. 3. After this the strap ends are tightened as indicated in Fig. 4 by means of the arrows, and finally the tool is actuated all the way to crimp the metal of the seal and strapping as indicated in Figs.

and 6. If main portion 2 is absolutely horizontal K as in the application previously referred to there is, at times, difficulty in directing the bending movement of the wings 3 from the position they occupyv in Fig. 2 into the position` shown in Fig. 3. I have found that, by making main portion 2 concavo-conveX with its conveXity extending in the same direction as upstanding wings 3, the difficulty set between the wings, the conveXity of said main portion extending in the same direction as the upstanding wings.
